We’re promising you the top online casinos in the UK, but how do you trust that they cut the mustard?
You don’t need to just take our word for it – we’ve got a checklist that’s as tough as they come.
At other sites, a below par casino might sneak its way onto the best casino sites list, just because it offers instant payments. But, once you sign up, you realise it only has a couple of hundred slots.
Not here!
All of the sites on our list of the best casinos tick off every single one of these criteria.
No casino makes it onto our list of the best casinos without a valid licence from the UK Gambling Commission. This licence is the gold standard in fairness, trustworthiness, and security – every casino you find on Hideous Slots that offers services to UK players will hold this licence.
We only recommend casinos that have large catalogues, filled with top quality games. A massive slots collection is a must, but we love to see a good choice of live casino games – and some classic table games too. The selections must contain offerings from the most popular providers, and must be updated regularly.
We only recommend casinos that offer lucrative welcome bonuses and packages to new players, and exciting rewards for returning and loyal customers too. In particular, we look for new and ongoing bonuses with fair terms and conditions, and appealing wagering requirements.
There’s nothing more frustrating as a player than depositing instantly but waiting ages to receive your winnings, so we prioritise the casinos that process withdrawals within 24 hours and send payments promptly. Some of the sites on our top casinos list even offer withdrawals within minutes.
Every now and again you run into a question when playing at online casinos – and you deserve answers quickly. All of our top 20 online casinos offer excellent customer support via live chat or email, with agents available around the clock. As an added bonus, many of them also offer extensive FAQs.
Trusting a casino with your bank details shouldn’t make you nervous, which is why we look for sites that take security seriously, prioritising SSL encryption, two factor authentication, independently audited games, and trusted payment providers. We want every player to feel safe and secure where they play.
Thanks to our YouTube channel with over 30,000 subscribers, we're in a unique position to listen to player feedback. This is something we consider when determining our top 20 online casinos – by thinking about what the players we speak to weekly consider the most important factors.
For UK, finding a reliable online casino is relatively simple, and this is because of what we mentioned above – the United Kingdom Gambling Commission, also known as the UKGC.
The best online casinos are licensed and regulated by the UKGC, which holds them to a certain standard of fair play and protection.
As the authority overseeing all gambling activities, both offline and online within the UK, the UK Gambling Commission have a mammoth task on their hands.
Established under the Gambling Act of 2005, the UKGC aims to ensure that gambling remains fair, transparent, and free from criminal activities.
Any online casino wishing to offer its services to UK residents must obtain a licence from the UKGC, which entails rigorous checks on the casino's operations, software integrity, financial standing, and its commitment to responsible gambling.
Spotting a UKGC licence on an online casino is always a reassuring sign – it ensures that the platform operates legally, with secure payment methods, fair games, and offers responsible gambling tools. Better still, all casinos with a UKGC licence must also display their bonus terms clearly.
This is why every UK casino on Hideous Slots will have this licence – we care about your safety.
Every casino that is recommended to readers on Hideous Slots undergoes rigorous testing from our team of experts.
This team have a combined decades of experience in the online gambling industry, meaning they know everything there is to know about licensing, bonuses and terms, payments, and the games offered.
We've added hundreds of written reviews for casinos to our website over the years, and checked even more that didn't make the cut.
Rather than sifting through all of the casinos we recommend, check out five of our current favourites below.
Mr Vegas continually makes our top casino lists, coming out ahead in everything from game selection to withdrawal times. Offering a lucrative 100% match bonus accompanied by 11 no deposit, no wagering free spins upon sign up, Mr Vegas has over 5,000 games and instant verification, so it's easy to see why it's so popular.
PartyCasino is another example of a casino that puts player experience above everything else. Players at PartyCasino can benefit from instant withdrawal methods and an exclusive bonus when joining through Hideous Slots. Add in over 1,000 games and 24/7 support, and it’s easy to see why it's one of our favourites.
If you love slots you'll find a comforting home at Mr Q, especially with their generous free spins welcome bonus exclusive to hideous slots players – made better by the fact that this is one of the only casinos that promises no wagering requirements on any of its bonuses.
If you like Mr Vegas, you'll love Videoslots – the sister site of Mr Vegas. Offering the same lucrative bonus as its newer counterpart, Videoslots processes withdrawals every 5 minutes, meaning you can receive your withdrawal in 10 minutes or less! This is all made even better with over 4,000 games and 24/7 support.
BetMGM has one of the most impressive bonuses in this list; offering no wagering free spins. This top-rated casino offers over 1,000 slots and casino games, swift payments and live chat customer support with real humans who'll help you out quickly, making it an easy choice for our experts.
More of us than ever are turning to mobile online casinos.
We’ve all got smartphones, so what could be more convenient than having access to all your favourite casino games, agt any time, right in the palm of your hand?
With UK casinos on mobile, you can still play all of the same online casino games that you would play on a desktop or laptop computer, but from your smartphone.
Nowadays, all online casinos offer basic functionality on mobile devices, but the best mobile casinos? They're the ones that have spent time optimising their website and user interface for mobile users, particularly in making the casino withdrawal process fast and easy.
Some casinos even have mobile casino apps where you can play casino games. With such slick mobile casino options, you need never miss a beat – or a bet.
Check out four of our favourites below.
It's imperative that you aim to stay safe when signing up to and using an online casino in the UK.
This includes safety surrounding your own data, and safety in your gambling habits.
There are a number of steps you can take to ensure this safety, and your future safety at online casinos through preventative measures.
We've outlined our six most important tips below, using our expertise to help you stay safe.
As we've discussed above, a reputable online casino in the UK will always be licensed by the UK Gambling Commission. You’ll be able to check the licensing details in the casino’s footer and ‘About Us’ page. This license also ensures casinos are audited for fairness by independent bodies like eCOGRA.
The licence alone is a brilliant start, but the presence of an SSL certificate is another important factor. Just look for a padlock icon next to the website URL in your browser on desktop or mobile – this tells you that all data transferred between you and the casino is encrypted and secure.
When you speak to casino support, be wary of the information you share. Support agents will never ask you for things like card numbers or security codes – they will only ever ask you for snippets of information (like the last 4 digits of your card number) to verify your identity.
Unfortunately, the sophistication of scams – in all industries, not just the casino industry – is on the rise, so exercise caution when you speak to anyone claiming to be from the casino. Casino workers will never call you to ask you for identifying information, so only share information when using secure channels.
Don't sign up to casinos that are not licensed by the UKGC, and be wary of sites that promise bonuses that are too good to be true. Thousands of free spins, tens of thousands in bonus money, claiming to have no wagering requirements on free money – these are all red flags that should make you reconsider.
Staying safe doesn't just mean security measures – it means gambling safely too. Always make use of any responsible gambling tools available, including deposit limits, loss limits and, if necessary, self-exclusion. Using these tools preventatively from the beginning can help you avoid a greater problem later.
Who doesn't love to be rewarded for their custom?
Whether you're picking up a free coffee after filling your loyalty card or taking 10% off your order thanks to a promo code, we all love to feel like we're getting something back when we're spending money.
The same is true for gambling at online casinos – where you can claim casino bonuses.
We've got plenty of guides to finding the best casino deposit bonus for UK players, so we don't need to go into too much detail here.
What you do need to know is that there are five main ways to be rewarded at casino sites in the UK.
Welcome bonus offers are your first window into a site's promotional approach, so play close attention to what you're being offered here. Sometimes, you'll need to make a minimum casino deposit to claim a bonus, other times, you could get a no deposit bonus where you can claim the bonus without depositing.
Finding free spins is always exciting, especially at a new casino site in the UK. These offers often come alongside cash offers, or they may come as a standalone offer, in which case you could receive more of them. Always look out for no wagering free spins or no deposit free spins, but be wary of any max bonus conversions.
Whilst not every online casino operates a loyalty program in the UK due to compliance difficulties, many of the best ones still do. It’s a little trickier to set up than standard promotions, but we love a loyalty program as it rewards you consistently and takes out the hassle of claiming promotions.
Loads of us are guilty of sleeping on the idea of player tournaments. It’s easy to ignore the pop-ups when they appear, but they can be a great opportunity to bag some extra cash. If you opt-in, you could be awarded prizes for the play you were planning to do anyway.
Finally, you may see special offers at top casino sites. These can be special because they're rare, or special because they just don't fit into any other category we've discussed – for example a one-off special offer to celebrate a public holiday, or you might find that you are awarded cashback on every deposit you make.
Choosing the right payment method can have a massive impact on your experience gambling online.
You could spend hours researching the best UK online casinos and reading guides like this until you find the best of the best.
Once you get there though, you could choose the wrong payment method and find that all of your hard work was pointless.
Payment methods can affect the minimum deposit you can make or how long your withdrawal will take.
They can even determine whether or not you are eligible to claim a bonus at certain online casinos, with some methods like e-wallets excluded from bonus promotions.
When we put together our list of the top UK casinos, we thought long and hard about payment methods.
In the end, we decided that a good mixture of options, with at least one fast or instant withdrawal method was the best option.
Read some more about the top three most popular payment methods below.
Debit cards remain the most popular option for players in the UK. It could be due to the convenience, the simplicity of use, or the just the reputation that precedes them. No matter the reason, these options, which include Visa, Mastercard and Maestro, remain the most popular options online.
E-wallets offer a layer of privacy to players that debit cards cannot. By keeping transactions separate from everyday banking, these options have risen in popularity in recent years. They're also on average one of the fastest methods for withdrawals – another reason they're so loved.
For yet another layer of privacy, it's prepaid cards. These are like vouchers – players load money onto them online or in stores, and then spend them to make deposits at online casinos. The only drawback for this method is that ou cannot withdraw to them, so players must choose another method for cashouts.
The archives of the top online casino sites are rich with stories of lucky players hitting life-changing sums.
Take, for instance, the British soldier who won a staggering £13.2 million from a 25p spin on the progressive slot game Mega Moolah in 2015 – a game known for its massive progressive jackpots.
This win not only made headlines across the UK but also broke world records of all the top online casinos at the time.
Such extraordinary events highlight the potential for huge returns from relatively small stakes, making online slot games particularly alluring.
These big winners become part of the casino's lore, often featured in promotional materials to highlight the possibilities that await casino players.
Some other notable wins include:
Finding one of the best online casino sites is only half the battle.
Once you're there, you want to enhance your experience – not necessarily by trying to win, but by making sure you get the most out of the features on offer.
There are a few different ways you can do this.
Our team have put together the following list of six things you can do to maximise your experience:
Choosing a new online casino is no small task, but we hope we’ve made it a little bit easier.
Our team work hard to put these guides together so you know what to look for when you're signing up to a new site.
From giving you tips on staying safe to explaining the bonuses you can expect to find, the aim of this information is to help you make up your own mind about what really makes the best casino site.
If you’d rather skip the leg work then that’s fine too – you can sign up to any of our top rated casinos trusting that our team of experts have signed off on it as a fair, safe and trustworthy brand.
We spent a long time deciding on which casinos would make it into our list of the top 20 casino sites, and we’re really happy with our selection.
If you do sign up to any of our recommended casinos, please make sure you play responsibly and deposit money you can afford to lose.
Any online casino site licensed and regulated by the United Kingdom Gambling Commission (UKGC) is guaranteed to be safe and fair, thanks to the stringent licensing conditions the casino must adhere to. By always checking for a UKGC licence you can help to ensure your experience will be completely safe and secure.
Absolutely – most modern online casinos offer mobile-friendly websites or dedicated mobile apps that allow players to enjoy their favourite games on the go. These mobile platforms are designed to provide a seamless gaming experience, whether you're using a smartphone or a tablet.
Withdrawal times vary depending on the online casino and the payment method chosen. E-wallets are usually the fastest method available with debit cards a close second, but we have a huge selection of fast withdrawal casinos – each offering at least one fast or instant payment method for withdrawals.
Online casino sites offer players convenience that can't be matched elsewhere. Whilst you would have to leave your home for a land-based casino, an online casino offers comfortable play – often with higher RTP values and a greater selection of games, including live dealer games to match the atmosphere you crave.
You can indeed. The best online casinos offer multiple ways for players to claim bonuses, including welcome offers that might be deposit bonuses or free spins, loyalty programs, player tournaments, or even special offers – like seasonal rewards or cashback. Always ensure you claim any bonuses you're offered.
